Static method in java code example
Example 1: static in java
using static before a method or variable we can access it by not creating a
instance of it.in the program we directly used student.cube(5)
class Calculate{
static int cube(int x){
return x*x*x;
}
public static void main(String args[]){
int result=Calculate.cube(5);
System.out.println(result);
}
}
Example 2: why we use static in java
In Java, static keyword is mainly used for memory management.
It can be used with variables, methods, blocks and nested classes.
It is a keyword which is used to share the same variable or method of a given
class. Basically, static is used for a constant variable or a method
that is same for every instance of a class
Example 3: what is static method
A static method belongs to the class rather than the object.
There is no need to create the object to call the static methods.
A static method can access and change the value of the static variable
Example 4: static in java
static keyword is a non-access modifier. static keyword can be used with
class level variable, block, method and inner class or nested class.
Example 5: do i have to use static methods in java main
Use a static method
when you want to be able to access the method
without an instance of the class
Example 6: Static method in java
We can declare a method as static by adding keyword “static” before method name.
Let’s see example on static method in java.
public class StaticMethodExample
{
static void print()
{
System.out.println("in static method.");
}
public static void main(String[] args)
{
StaticMethodExample.print();
}
}
